R-22 air conditioner?

Question

Looking for an informed opinion

I have a house in So Cal – 100 plus temperatures.

Current renter has tried to run A/C all night and it stops

Apparently the evaporator ices up.

I’ve told him to stop till I find out what gives but he continues to use it at night.

I look under furnace and find wet floor.

On a 100 degree day with 75 degree air inside and 65 degree wet bulb, I measure 50 psig on the suction side of the compressor.

Is this evidence of low freon?

I don’t plan to add my own – don’t have epa 308 license – but would like to know what gives since I don’t particularly trust local AC guys – some of whom operate by feeling the pipes and others of whom want $50 per pound for R-22.

My concern is that if freon is too low may ice up evaporator with result that liquid goes back to compressor – which I understand can break the compressor– and also I understand that compressor may not get adequate lubrication; but if too high may harm the compressor in some other way.

Looking for help

Answer 1

if the floor is wet you need to change your air filter and you will need a hvac tech to add freon to the system

Answer 2

you are correct also clogged evap coil will also ice up clean both coils inside and out to get it right

Answer 3

50 psi will freeze up. with 100 degree ambiant air temp, you re probably around 85 psi.  feel free to email me if any questions

Answer 4

The best "opinion" I can give ya, would be to take that wealth of information to the manufacture's web site.
